Musician Courtney Love has launched a strongly worded and rather vulgar campaign against the use of her deceased husband's likeness in Guitar Hero 5, claiming that she is "going to sue the shit out of [Activision]" over Kurt Cobain's in-game appearance.

A digital rendition of the Nirvana frontman performs "Smells Like Teen Spirit" during the game's career mode, after which players can use his likeness to perform any in-game song (such as "Play That Funky Music") in any capacity (drums, guitar, vocals).

Love says she "never signed [off] on the avatar" and adds "I think Kurt would despise this game alone let alone this avatar." Activision previously told Rolling Stone that it had gotten approval from Love, Nirvana drummer Dave Grohl and Primary Wave Publishing to use two Nirvana tunes and Cobain's likeness in the game.

"Courtney supplied us with photos and videos and knew exactly what she wanted Kurt to look like," the company explained. "She picked the wardrobe and hair style, which turned out to be the 'Teen Spirit' look, then we went back and forth over changes."

Cobain's not the only real-life rock star to appear in the game. Digitized versions of Johnny Cash, Carlos Santana, Matt Bellamy (Muse) and Shirley Manson (Garbage) are also featured, and can also be used in any song and in any capacity once unlocked.
